Comment 4 for bug 1740289

I saw the exact same messages when running bionic installed through latest cdimage builds of ubuntu. It's visible on boot almost every time (although once I noticed it was not present in the boot logs and dmesg, so it might not be reproducible 100% of the time).

I tried the latest mainline kernel, in this case: 4.15.0-041500rc8 and the issue seems to still be present (output still there). Confirmed I'm running the 4.15 kernel.
Please note my testing environment is a standard kvm instance.

Tagging.
